This invention relates to a proof press, p articularly useful inconnection with printing proofs without the necessityv of enteringV andpn locking the forms in a printing press and 5 with which the type,illustration plates and the like are held in a chase located at theupper side .of a movable truck or turtle as it is called, which may bemoved into .the ma-A chine and automatically properly located machineand then secured against movement, after which the type may be inked,paper drawn over the inked type and the paper pressed against the typeby n means of a suitable movable platen roller so as to print a proofsheet which may then be examined for mistakes or the like, the turtlewhich carries the chase and the make up type and illustrative platestherein being Y m quickly and easily removed from the machine by merelyrolling the same over the floor away therefrom.

This invention is concerned with many novel constructions andcombinations and ar- 1 rangements of parts for effectively attaining themain purpose of the invention as stated.

n '3K0 against the inked type is of a floating character so as toconform to the chase and the type upper surfaces, within certain limits,

it is not necessary at all to pay any attention to irregularities in thefloor or minordiiferences inthe height and level of the different trucksor turtles which may be introduced into the machine, or to watch out fordifferent leveling conditions which may come from a wear of the bearingsorvouter surfaces of the casters on'which the turtle is mounted as thefloating character of the frame which carries the inking mechanism andthe platen roller permits the same to conform to the surface of the typewhich is to be inked and f against which the paper is to be pressed bythe roller. v

There are many other features of construction and novelty in themechanism for the effective inking of the type and movement of theplaten roller over the paper above the type; for the elimination of inkat the upper edges of the ends and sides of thechase; for transferringink to the type inking rollers simultaneously with the movement oftheplaten roller over the paper to press it against the type previouslyinked or, if desired, for applying and transferring ink to said typeinking rollers separately and distinct from any movement ofthe platenroll'- er, all of which will be apparent upon understanding theinvention from the following description taken in connection with theaccompanying drawings, in which,

Like' reference' characters refer to like parts in the different figuresof the drawings.

In the construction of the machine a lower supporting` frame is providedwhich in construction includes two substantially independent and `spacedapart elongated vertical frames l between which the turtle or truck 95which carries the chase with type therein is adapted to be placed. Theseside frames 1 are of a substantial character and are designed to befirmly located and secured on a floor; and thereY are substantially nocross 100 connections between said side frames except in so far as theframes are used to support the ends of a rock shaft, hereafterdescribed.

Over the two spaced apart frames 1 a floating frame structure is mountedupon which substantially all of the mechanism for inking the type andoperating the pressure platen roller is secured. This floating frameincludes two elongated sides 2 located one directly over the upper endof each of the frames 1. The sides 2 of the floating frame are connectedtogether at front and rear by cross rods 3. Various other rods andshafts, on which the mechanism carried by the floating frame is mounted,also extend between the sides 2 and at what may be termed the Jfront endof the machine are vupwardly extending brackets 4, one attached to eachof the sides 2 of the floating frame, over which an angular sheet metalcover 5 is disposed and secured which in practice is to serve as asupport for a sheet of proof after it has been printed in the machine.

The sides 2 of the floating frame have a floating connection with thelower side frames 1 through pins G connected to and extending upwardlyfrom the frames 1 into suitable sockets at the lower sides of the sides2 of the floating` frame, coiled compression springs 7 being disposedbetween the frame members 1 and 2 which in a measure support and balancethe weight of said sides 2 of the floating frame. There are two of thesepins with compression springs around them at each side of the machinewhich are symetrically located with respect to a central transverseplane substantially midway between the ends of the machine.

A means is provided Jfor raising and lowering the floating frame withrespect to the stationary side frames 1 below. To this end a pairroftoggle links 8 are pivotally connected at their upper ends at 9, one ateach side of each of the lower stationary frames 1 and at their lowerends have pivotal connection at 10 to'another p air of toggle links 11which extend downwardly and have a pin or rod 12 passing through theirlower ends, at the same'time passing through a vertical slot 13 ,in ahorizontal frame member ot the lower stationary side frame 1. Two bars14 are pivotally connected at 15 at their upper ends adjacent the lowerside of each floating side frame member 2 and extend downwardlyalongside the toggle links. The pin or rod 12 at its ends passes throughthe bars 111 which are continued below said pin or rod 12 between twoguides 16 projecting laterally from the same horizontal frame member ofthe side frame 1 in which the slots 13 are cut. The toggle linkconstructions and the bars 1.4 are located in a transverse verticalplane substantially midway between the planes of the 'pins 6 previouslydescribed.

A horizontal rock shaft 17 (see Fig. 1) extends between and is mountedat its ends on the side frames 1 to which, adjacent one ot said sideframes, a bell crank lever 18 is permanently secured having an upwardlyextending arm 18a. An equivalent arm 18a is connected to the rock shaft17 adjacent the other side frame 1. Rods 19 extend from the upper endsof the arms 18a to the pins 10 at the knuckles of the toggle leversdescribed and in practice a turnbuckle adjusting nut 2O is disposed ineach rod 19 so as to adjust the length of said rods as may be desired.

The forwardly extending arm of the bell crank lever 18 has a verticallink 21 pivotally connected at its upper end thereto which at its lowerend is pivotally connected to a foot lever 22 located at the inner sideof one of the lower side frame members 1 and pivotally mounted at 23thereon at a point between the ends of said foot lever. The foot leverat its ends has outwardly extending foot engaging pedals 24 and 25 whichextend through openings in the frame 1 for ready operation by the footof the operator of the machine.

The turtle or truck which carries the chase within the sides of whichthe set-up type is disposed is adapted to be rolled between the spacedapart sidesot both the un der supportmg frame and the floating frame andunder the rear cross rod 3. This truck includes a substantiallyhorizontal top 26 supported at its corners by deper ding vertical postsor legs 27 which are connected by cross tubular bars 28 and longitudinaltubular bars 29. Casters or rollers are mounted at the lower ends of thelegs 'for readily moving the turtle over the floor and into properposition with reference to the machine. On the upper side of the table26 the chase 30 is placed within which is the set-up ot type plates forillustrations and the like as indicated in out-line at 3l, the spaceshown between the inner sides of the chase and the outline of the typebeing for the usual printers 'machinery for securing and holdingthe typein the chase. L

On the floor near the rear ot the machine and between the sides thereof,a supporting bracket 82 is secured through the upper end of which ashort shaft is mounted having a cam Enger 33 connected to its front endand a foot pedal lever 34 to its rear end as shown. lVhen the turtle hasbeen moved to position between the sides 1 of the lower frame bvoperating the foot pedal in one direction the cam finger is broughtagainst vthe rear cross bar 28 ot the turtle frame thereby securing itin position against rearward movement; The release of the turtle isaccomplished bv operating the foot lever in the opposite direction so asto bring the cam finger below the cross rod 28 which it operativelyengages.

When the turtle is rolled into 'the machine vbetween the sides thereofone of 'the front corners comes against an 'incline 35 (see Fig.

2) which has the eectof moving the turtle toward the other side of themachine and brings the corners of the chase located at the upper side ofthe turtle at its front ends under overhanging brackets 36 through whichadjusting screws 37 pass, while the rear corners come under somewhatsimilar overhanging brackets 38 having like adjusting screws 37 passingtherethrough. The

side of the top of the turtle opposite that at which the incline engagesis thereupon brought against a side gauge bar 39 (see Fig. 2) which iscarried by the adjacent side 2 of the floating frame.

A member 40 is pivotally connected at 41 to one of the brackets 38, asshown in Fig. 2, and carries two rollers 42 and 43 adapted to engageagainst a side and at the outer end of the chase 30. The member 4() hasa curved slot 44 therein. A hand operated lever 45 passes over asupporting bracket 46 attached to and extending forward from the rearrod 3 and is pivotally mounted between its ends at 47 on the bracket,and atits front end has pin 48 entering the slot 44, By turning the handlever to the position shown in Fig. 2 the rollers 40 and 43 engage theouter end and an adjacent side of the chase 30 and move the turtlecarrying the chase into proper position against the gauge bar 39 andunder the overhanging brackets 36 and 38 whereupon by propermanipulation by the foot lever 22 the floating frame may be lowered sothat the lower ends of the adjusting screws 37 enga-ge against andsecurely hold the chase and the turtle on which it is located againstmovement. u

The. front overhanging brackets 36 are mounted on two parallel crossrods 49 which are spaced apart a short distance and on which shortrollers 50 are mounted. A serrated cutting bar 51 is carried by andbetween the brackets. The paper 52, which is to be lead over the chaseand type, is drawn upwardly between the rollers 50 from a roll of papermounted on a shaft- 53 near the lower front portion of the machine, theshaft being mounted at its ends in supports 54 attached to the Hoor andlocated between the spaced apart sides of the lower frame. It is evidentthat the paper may be drawn under neath the cutting bar 51 and over thechase an-d type and after the proof has been printed the paper may becut 0E against the serrated edge of the cutting bar 51.

A horizontal shaft 55 is mounted for rotation on and between the frontend portions of the sides 2 of the upper Hoating frame. Said shaftextends through the sides and is equipped with sprocket wheels 56adjacent its ends, oneend of the shaft being continued and squared forthe reception of a crank whereby the shaft may be manually turned.Endless chains 57 pass around the sprocket wheels 56 and lie along theouter sides of the flo-ating frame extending to the rear and passingaround sprocket wheels 58 mounted on short stub shafts which extendthrough the sides of the oating frame.

In the lengths of the chains 57 vertical end members 59 of aV platenroller carriage are riage, is also equipped with carrying rollers 61awhich ride on the upper sides of the sides 2 of the floating frame whichserve as tracks for the rollers 61a.

The carriage is completed by cross rods62 which connectthe members 59 ofthe carriage. On these cross rods directly in front and also back of theroller 61a are other carrying rollers 63 which ride on the upper edgesof the sides 2 of the floating frame. The end members 59 extenddownwardly along the outer sides of the sides 2, as shown in Fig. 3, andare equipped with other rollers 64 which extend inwardly under trackflanges 2a projecting outwardly from the sides 2 of the floating frame.It is evident that by turning the shaft 55, the chains 57 will beactuated in unison and draw the car-V riage with the platen roller backand over the chase and type and, the lower surface or edge of the roller6l, being in substantially the same plane as the upper sides of thechase and type, the paper will be pressed against the type; It should benoted in this connection that the length of the rplaten roller 6l isless than the distance between the inner sides of the sides of the chase30 so that the paper is `not pressed against the upper edges of thesides of the chase but is only pressed-against the type.

An inking roller 65 is carried on a horizontal shaft 66 which extendsbetween and is mounted at its ends on the sides 2V of the float-ingframe. The inking roller 65 is mounted forrotation but for no othermovement. Y A gear -67 (see Figs. 6 and 7) is secured to the shaft 66and is in mesh with a cooperating gear 68 fixed on a short shaft 69which is rotatably and slidably mounted through the adjacent side 2 ofthe floatingv frame, its inner end having a rotatable mount in asupporting bracket 7 O connected to said side 2. A spring 71 around theshaft 69 normally moves the gear 68 to clutch conneet it with a combinedgear sprocket wheel 72 and retaining disc 73 loosely mounted on theshaft 69 between the gear 68 and the side 2 of the floating frame. Theedge of the disc 73 enters a recess in the bracket 70 to hold the wheel72 in place. The shaft 69, at its outer end, is squared to receive acrank and on attaching the crank, if desired, the shaft may be movedinwardly to disconnect the gears 68 and 'T2 whereby the inking roller 65may be rotated without affecting any of the other mechanism.

A sprocket chain 74 passes around the wheel 7 2 and extends forwardlyand upwardly therefrom to and around Aa sprocket wheel 7 5 on the shaft55. lt is evident that when the shaft is turned manually by attachingthe crank at its end there is a si1nultaneous rotation of the inkingroller with the movement of the platen roller Gl over the machine.

An endless chain 76 is disposed at the inner side of each of the sides 2of the floating frame, said chains at their rear ends passing aroundsprocket wheels 77 mounted near the rear ends of sides 2 and at theirfront ends around sprocket wheels 78 secured to a cross shaft 7 9 whichextends between and is mounted on said sides 2, one end of the shaft 7 9extending through and beyond the adjacent side 2 and being squared toreceive a crank. rl`he chains I6 pass above the rods 49 and their upperruns may then be ydirected downwardly to the sprocket wheels 78substantially in accordance with the inclination of inwardly extendinginclined tracks 8O formed at the inner sides integral with the sides '2of the lloating frame.

An inking roller carriage is connected with the chains 76 to be movedthereby. Each end of the carriage includes two sections 8l located inlongitudinal alignmentand pivotally connected at their adjacent ends. Onthe sections 8l of the carriage ends rollers 82, to traverse the upperside of said sides 2 and inclined 'tracks 80, are mounted. The free endsof the sections 8l are connected by cross rods 83. vOn these cross rodsinking roller supporting members 84, similar to the sections 8l andpivotally connected at their adjacent ends7 are mounted. Gn and betweenthe parts 8l two pairs of inking rollers 85 are disposed and rotatablymounted as best shown in Fig. 2. Ink spreading rollers'86, one for eachpair of inking rollers 85,are located above and between each )air ofinking rollers and mounted at their ends on the respective parts 84 fromwhich inclined cam members 87 project to engage with the similar camlike ends of the spreading rollers 86 whereby when the rollers 8G arerotated by frictional Contact with the inking rollers 85 they are alsosimultaneously reciprocated short distances.

lvlieu the type inking rollers 85 are to be inked from the main inkingroller G5, the shaft 79 is turned so as to bringthe type inl*- ingrollercarriage onto the inclined tracks 80 with the inner rollers of the twopairs of type inking rollers bearing against the surface of the maininking roller 85 as shown in Fig. 5. a'lurning the roller G5 causes aturning of the rollers 85 in contact therewith while the other rollers85 are driven from the first rollers 85 through the spreading rollers 86and the ink onthe surface of the main inking roller 65 is carried'to thetype inking rollers 85 and through the reciprocatory action of thespreading rollers 86 and type inking rollers 85 are evenly covered ontheir surfaces with ink.

ln order to hold the type inking carriage against movement during theinking operation one section 8l thereof is provided with an upwardlyextending dog 88 with which a latch dog 89 is adapted to engage. Thelatch dog is on one arm 90 of a bell crank lever which is mounted forpivotal lnovement at 91 on the adjacent side 2 of the machine and has idownwardly extending arm 92 with an outwardly projecting linger engagingportion 93 for the operator to release the latch when the inkingoperation has been performed and it desired to move the type inkingrollers back over the machine to ink the type 3l.

lhe type inking rollers on their rearward movement for the purpose ofinking the type 3l must pass over the ends of the chase 80, the uppersides of which are in the same horizontal planevwith the type. In orderthat ink will not be transferred to the upper sides of the enes of thechase, raised projections or bumps 94 are secured to the upper sides ofthe sides 2 of the Heating frame for the carriage rollers 82 to rideover and are positioned so that the type inking roller carriage islifted to raise the type :inking rollers 85 above the ends of the chaseb-ut permitting the type inking rollers to come back to lower positionwhen the type 31 is reached thereby keeping the upper sides of the endsof the chase free of ink at all times yet causing the face of the typeto be completely inked with the passage of the type inking rollercarriage. It will be also noted that the length of the type inkingrollers 85 is less than the distance between the inner sides of thesides of the chase so that no ink is applied to the upper sides of thesides of the chase and, therefore, when paper is put over the type andchase and the platen roller carried over the paper to press it againstthe type, no ink is transferred from the chase to the paper.

This construction of prooi:l press described is one which has provedvery practical and successful. The turtles or trucks, ach with a top 26,which may be an imposing table, are very readily rolled into the machinebetween its sides, quickly secured in proper position and, due to thefloating character of the upper frame of the machine on which all of theessential mechanism of the machine is mounted, variations in the heightsand levels of the imposing table 26 and the chase and type thereon areautomatically taken care of as the floating frame with its mechanismwhen lowered, is `brought to rest against the upper sides of the chaseat its corners when the adjusting screws 37 engage thereagainst. Theinking of the inking rollers may be accomplished by itself by engagingthe shaft 69 with a crank and pushing the saine inwardly,

` as is desirable when the inking of the type for the llrst proof sheetis to be done. The inking roller carriage is then moved to the rear overthe type. Then when the type inking roller carriage is moved back to theposition shown in Figs. l and 5, latched in position, by turning theshaft 55 the platen roller is moved back over the paper which in themeantime has been drawn upwardly and over to the rear to cover the inkedtype and at the same time the type inking rollers 85 are again inked forthe next succeeding operation. After the platen roller has performed itsfunction and has beenreturned to the front of the machine, the proofsheet printed is severed by engaging the paper against the serratedknife edge at 5l and thrown upwardly over the sheet metal plate 5, theturtle released and run out of the latch, the next one put in its placeand the operation repeated as many times as may be necessary.

The invention is capable of embodiment with many variations in specificdetail of construction from that shown in the drawings and is not to belimit-ed specifically thereto. rlfhe invention is `defined in theappended claims and is to be considered comprehensive of all forms ofstructure coming within their scope.
